I ruff the second heart, cash a top spade and cross to the spade J, hoping for 2-2, but not being that worried about the 1-3.
I now lead a low diamond, inserting the 9.
I am not out of the woods yet. But even if this loses to the 10, I have reasonable prospects since he is endplayed. I won't go into details, because there are lots of forks in the road depending on what spot cards are played and when. For example, if he switches to a small club, do I play for split honours? I think so, since QJ tight on my right is improbable, but if the diamond 8 had appeared on the first round, I would probably play for Q8 tight on my right and exit the diamond K.
I will probably need to find LHO 1=6=3=3 but that is quite likely since with 6-4 shape, expecting 4 card support more often than not, he might have blasted 4

♠. I mean x AKxxxx A10xx xx looks like a reasonable 4
♥ to me, in an effort to shut out LHO and steal the contract (not to mention that a good dummy would make it cold).
An expert would usually switch to a club honour from Hxx or QJx, to give me a losing option but I concur with Micky's assessment that the opps are likely to be bad based on their (unusual) signalling method). Plus it is MPs and most MP opps are, in most fields, bad
