I'm being driven mad by making the "muddled thinking" or concentration type mistakes which I usually avoid face to face. I've made 5 in 2 sessions which is normally several months worth, maybe a year's.
I'm really not sure what to do about it, example from my last set (matchpoints).
W leads the K♥, you've noticed EW don't signal much, E plays low, you win the ace, ruff a heart and play a diamond, E wins the K and plays a club, you win on the table, play off ♠Q which holds, play a diamond to the Q, and ruff your last heart, surprisingly overruffed by E, who now leads a diamond, what now ?
W appears to be 2722 or 1723 or 1732, what do you think is the best bet ?
