I will say my opinion: 6♦ looks OK to me. 6♥ isn't pass correct or something. My partner knows that I have ♥ or ♦ but since his RHO has bid 6♦ he knows I am with ♥ which also means to the opponent that my partner has honours in the two other suits. The X in my opinion means partner I have a trick which is most likely A♣, so 6♠ is reasonable.
I think I must explain some things. 3♠ is Gambling (can be a major) with maximum one side Queen. 6♥ means that the partner of the 3♠ opener has found which is the suit (♥). I am not quite sure what the X of 6♥ means, I was bidding with the 3♠ hand and I still won't post what happened in this board (it was truly on vugraph).

[hv=pc=n&e=sakjt8hdakqj643cq&d=w&v=0&b=8&a=p3s(Gambling%2C%20can%20be%20a%20major%2C%20solid%20suit%2C%20max%20one%20side%20Q)6d6hdp]133|200[/hv] Second problem: What do you bid assuming you overcalled 6♦ and this is what happens (this is what happened in our table). IMPs.
I think it is pretty much time to say the outcome. [hv=pc=n&s=s9hat9832dk732c83&w=sjt76532hdcakj976&n=sakhk6daqjt96ct42&e=sq84hqj754d854cq5&d=s&v=b&b=7&a=2h3h4hpp4sdppp]399|300[/hv] I must admit that now I disagree with my bid of 3♥ but that's what happened at the table and 4♠x+1 was the score which was mostly seen on all the tables.
[hv=pc=n&w=sjt76532hdcakj976&n=sakhk6daqjt96ct42&d=s&v=b&b=7&a=2h]266|200[/hv] You are dealt a beauty in second seat, South preempts with 2♥, both vul. What do you bid with West's hand? Then, what do you bid with North's hand over West's interruption?
