Bidding: North opens 1H – 1S; 2C – 2D; 2H – all pass
MrQ: Shouldn’t North bid 2S instead of 2H? When South rebids 2D (whether natural or forcing), South pretty much denies 3-card heart support so North knows that there is at most 5-2 fit in hearts and at least 4-3 fit is spades.
Guru: South’s bidding was terrible. I was also South and bid 2S, where it was played. Whether or not 2D is fourth suit forcing (I must say I HATE it as FSF in that sequence) the obvious bid for South is 2S, maybe even with two good spades not three but North’s bidding almost certainly guarantees five spades.
