Excerpts from ACBL/BBO Individual
(Page of 3)

I advertised several times playing against bots as a great lab for exercising various coups due to the special quality of bots defense. Not this time - in this tourney I faced 72 boring hands. The only hand I squeezed bots I misclicked; I misclicked another time, for the total shaving of 1.1% from my final score. I can't complain though about playing a boring set --- I defended only four hands and for two of those it was a human error of not competing high enough. 'The best hand' feature implies that you will declare very often yet it was lots of luck to play this set of hands since in defense getting a score way above average is rather difficult.

I show three hands I find instructive for playing against bots counting N. Robot as your third opponent. For those who want to hone up their bot skills, I recommend playing in bbo 55% tourneys - you play against much better crowd than in $0.25 tourneys with the fierce competition for bidding contracts that exploit bots defense. The main thing those tourneys may teach you botwise is what level of risk is reasonable in the cyber bidding-crime environment.

Here's my pet bot 1N - a six-card minor, at least decent if points are wanting a bit and 3-3M, 11-17HCP. Reaching 3N was worth 89%; two other players reached virtually cold 6.

The hand above demonstrates an instance of making bots useful in slam investigations. Driving to slam is not clear from the South position while you may imagine some hands where you are not safe in 5s. Bot with the maximum raise generally cooperates, so giving him a chance is a good bet. Reaching slam and playing the trump suit to split was worth 81%. The same technique applies after a limit raise in a major - if you q-bid, bot with a good hand will b-wood. Of course, bot hand appraisal may be funny - it b-wooded me once after 1-3/4 with a queen-high(sic) hand but with five-card support and a stiff. Still, bidding a que instead of b-wood allows stopping in game when five-level is onerous way more often than getting a silly b-wood from N. Robot. 

Finally, a really lucky hand.

I bid 2 as a lead inhibitor --- bots trust your bids, e.g. bidding 2m with three babies is a good idea if you want to sail to 3N in a 2/1 sequence (two babies are a tad risky since a bot would remove your 3N to 5m with a five-card fit). N. Robot unexpectedly raised s but luck was with me since it passed 4. Being in s instead of NT yields 89%; playing a  at trick two gave me a top. Note that if you are in 3N as South and play it exactly as I did in 4 and E. Robot continues s when in with a  trick, you score the same 12 tricks yet it is a stupidly risky play nobody tried.
